The industry's most demanding performance-based certifications, CCP evaluates and recognizes a candidate's mastery of the technical skills most sought after by employers

CCP Data Engineers possesses the skills to develop reliable, autonomous, scalable data pipelines that result in optimized data sets for a variety of workloads.

CCP Data Engineer Exam (DE575).

Required Skills

Data Ingest

The skills to transfer data between external systems and your cluster. This includes the following:

Import and export data between an external RDBMS and your cluster, including the ability to import specific subsets, change the delimiter and file format of imported data during ingest, and alter the data access pattern or privileges.

Ingest real-time and near-real time (NRT) streaming data into HDFS, including the ability to distribute to multiple data sources and convert data on ingest from one format to another.

Load data into and out of HDFS using the Hadoop File System (FS) commands.

Transform, Stage, Store

Convert a set of data values in a given format stored in HDFS into new data values and/or a new data format and write them into HDFS or Hive/HCatalog. This includes the following skills:

Convert data from one file format to another

Write your data with compression

Convert data from one set of values to another (e.g., Lat/Long to Postal Address using an external library)

Change the data format of values in a data set

Purge bad records from a data set, e.g., null values

Deduplication and merge data

Denormalize data from multiple disparate data sets

Evolve an Avro or Parquet schema

Partition an existing data set according to one or more partition keys

Tune data for optimal query performance

Data Analysis

Filter, sort, join, aggregate, and/or transform one or more data sets in a given format stored in HDFS to produce a specified result. All of these tasks may include reading from Parquet, Avro, JSON, delimited text, and natural language text. The queries will include complex data types (e.g., array, map, struct), the implementation of external libraries, partitioned data, compressed data, and require the use of metadata from Hive/HCatalog.

Write a query to aggregate multiple rows of data

Write a query to calculate aggregate statistics (e.g., average or sum)

Write a query to filter data

Write a query that produces ranked or sorted data

Write a query that joins multiple data sets

Read and/or create a Hive or an HCatalog table from existing data in HDFS

Workflow

The ability to create and execute various jobs and actions that move data towards greater value and use in a system. This includes the following skills:

Orchestrate a workflow to execute regularly at predefined times, including workflows that have data dependencies

What should you expect?

You are given five to eight customer problems each with a unique, large data set, a CDH cluster, and four hours. For each problem, you must implement a technical solution with a high degree of precision that meets all the requirements. You may use any tool or combination of tools on the cluster (see list below) -- you get to pick the tool(s) that are right for the job. You must possess enough industry knowledge to analyze the problem and arrive at an optimal approach given the time allowed. You need to know what you should do and then do it on a live cluster under rigorous conditions, including a time limit and while being watched by a proctor.

Who is this for?

Candidates for CCP Data Engineer should have in-depth experience developing data engineering solutions and a high-level of mastery of the skills above. There are no other prerequisites.

What is the best way to prepare?

The CCP Data Engineer exam was created to identify talented data professioanls looking to stand out and be recognized by employers looking for their skills. Outside of having hands-on experience in the field, it is recommended that professional looking to achieve this certification start by taking Cloudera's Spark and Hadoop Developer training course
